How to calculate the "Due date" based on the "Start date" + "Duration" (custom field)

Alanis, Hans

I created a number custom field called "Duration" that I want to use to calculate the Due Date, for example Due Date = Start date + Duration.

I created an automation but when I update the Start date, the value on the Due Date field disappears (if not empty) and the Automation Audit Log shows no errors and a status of success.

This is the Smart Value I am using:
{{issue.Start Date.plusBusinessDays(issue.Duration)}}

The fields that I am using are:
Start date
Duration
Due date

If I use the following Smart value, it works fine, and the Due Date field gets updated:
{{now.plusDays(7)}}

Any idea what's wrong?

Hi @Alanis, Hans 

I was able to re-create the issue you are facing. The due date got empty when i edited the start date while there was no value in the duration field. so when there is no value in the duration field and then you edited the start date the due date value will be empty. can you please check the issue if there was value on the duration field. The smart value is not the issues it is working as expected. 

Thank you.
